Co-evolution and Contradiction: A Diamond Model of Designer-User Interaction

This paper explores how the Engineering Design process might balance conflicting constraints of technical product design and the social demands of users. Building on a generic 2D map for innovation in design from the author’s previous work, a prototype 3D Diamond Model is presented to help structure conversations between Designers and Users – or indeed any other group with apparently opposing aims

A comprehensive model for ultrawideband propagation channels

This paper describes a comprehensive statistical model for UWB propagation channels that is valid for a frequency range from 3-10 GHz. It is based on measurements and simulations in the following environments: residential indoor, office indoor, built-up outdoor, industrial indoor, farm environments, and body area networks. The model is independent of the used antennas. It includes the frequency de

An alkaline active maltooligosaccharide forming alpha-amylase from Bacillus halodurans

The East African Rift Valley contains a number of soda lakes, which represent some of the most stable, naturally occurring alkaline environments on earth. Alkaliphilic microorganisms found in these habitats have attracted a great interest due to their ability to produce extracellular enzymes that are active and stable at high pH values for industrial applications. Starch hydrolysing alkaliphilic b

VHDL vs. Bluespec System Verilog: A case study on a Java embedded architecture

This paper compares two hardware design flows, based on the classic VHDL on one side and the relatively new Bluespec System Verilog (BSV) on the other side. The comparison is based on a case study of a Java embedded architecture, comprising a Java native processor and a memory management unit. The processor is a micro-programmed, pipelined, Java-optimized processor (JOP), initially written in VHDL

Fabrication and Characterisations of New Ultra-thin Silicon Detectors as Pre-Cell Hit Detectors for a Cell Irradiation Facility at LIBAF

For the development of single–ion irradiation system for living cells at the Lund Ion Beam Analysis facility (LIBAF) newly developed pre-cell (PC) detectors have been investigated. Central to the thesis is the fabrication and initial characterization of more than 100 ultra-thin silicon detectors having different thicknesses down to 5 μm with active areas ranging from 0.71 to 0.172 mm2, to be used

Jourtjänstgöring: påverkan på katabola processer och återhämtning

Anestesiläkare rapporterades i en svensk studie ha en högre mortalitet än genomsnittet av läkare. Detta fynd har dock ej kunnat reproduceras i motsvarande studier i de övriga nordiska länderna. Likväl har det spekulerats i om den angivna överrisken bland svenska anestesiläkare kan relateras till gruppens jourarbete med höga krav, nattarbete och stress. Kunskapen om hälsoeffekter av läkares jourarb

Laplace distribution models for road topography and roughness

Gaussian models are frequently used for road profiles. However, these models are often only valid for short sections of the road. Here we present a comprehensive approach to describe various aspects of road surface/elevation by using extensions of Gaussian models arising from random gamma distributed variances. These random variances result in the Laplace distribution and thus we refer to the so d

Teknik och förståndshandikapp

Den här boken är fylld av exempel på hur man med hjälp av ny och gammal teknik kan förbättra situationen för människor med förståndshandikapp.Man visar hur teknik, pedagogik och fantasi kan öka utrymmet för både självständighet och eget skapande.
